Which of the following is not a function of glycogen in the body?

Glycogen serves primarily as a form of energy storage in animals, providing readily available glucose for metabolic processes. When the body needs energy, glycogen can be broken down into glucose and released into the bloodstream, highlighting its role in both energy storage and glucose release.

The role of glycogen does not include protein synthesis, which is the process of building proteins from amino acids, a function primarily carried out by ribosomes and the cellular machinery involved in translation. Glycogen is not directly involved in the synthesis of proteins, which distinguishes this function from the roles it does play regarding energy storage and regulation. Additionally, glycogen contributes to metabolic regulation by influencing glucose homeostasis and energy balance within the body, responding to hormonal signals such as insulin and glucagon.
